Automatic exhaust packaging realizes the automatic exhaust function mainly through the one-way valve and is applied in coffee packaging, microwave processing food packaging, special packaging of dangerous goods etc.. By using one-way valve, vacuum packaging pumps the gas out of the package and its main application is in family vacuum storage bag. Inflatable packaging has forms of inflatable bag and an inflatable cushion packaging, the charging function is realized mainly through the one-way valve while its cushioning properties depend on the inflatable volume, length and width size of the buffer pad, the barrier properties of the thin film and the related environment temperature and it is mainly used in packaging for small electronic products, liquor, fragile valuables and precision instruments.关键词
